Answer: 5,242 J

Explanation:

Step by step:

The formula for this is Q=mcΔT

Find out your values and then plug-and-play.

Q= unknown (energy amt we need to find out)

m= 167g

c= 2.093 J/go°C

ΔT= -20.0° + 15° would give you  -5.0°

Plug into the equation for Q=(167g)(2.093 J/g°C)(15°C).

Solve and you get 5,242 J.

hope this helps!!
